NASA astronauts replaced a coolant tank the size of a small car late Thursday on the International Space Station.
During the course of about six and a half hours, Olivas and Christer Fuglesang spacewalked outside the space station to install the new 1,7--pound ammonia coolant tank, Space.com reports, and stick the old one 1,300-pound one back about shuttle Discovery.
"If you can almost picture someone handing around a Mini Cooper car between the two of them, it's about the similar weight and mass of the tank they were handing between each other," said Zeb Scoville, lead spacewalk officer for Discovery's mission, in the article.
As they did this, the two kept their eyes on a large piece of space junk that came off a 3-year-old European rocket; it turned out to pose no threat to the astronauts or the shuttle, according to the report. (Image credit: NASA TV)
